I/O Lines Description
Power-On
Detector
The PM interrupt line is connected to one of the interrupt controllers internal sources. Using the
PM interrupt requires the interrupt controller to be configured first.
In AT32UC3L, the HSB shares source clock with the CPU. Write attempts to the HSB Clock
Select register (HSBSEL) will be ignored, and it will always read the same as the CPU Clock
Select register (CPUSEL).
The PM bus interface clock (CLK_PM) is generated by the Power Manager. This clock is
enabled at reset, and can be disabled in the Power Manager. If disabled it can only be re-
enabled by a reset.
The Shutdown mode is only available for the “3.3V supply mode, with 1.8V regulated I/O lines“
power configuration.
